Description

What does an air dryer valve do?

This air dryer valve plays a critical role in the pneumatic brake system by removing moisture, oil, and particulates from the compressed air supply. By ensuring a consistent flow of dry air, it protects downstream components from corrosion and prevents system failures in demanding heavy commercial vehicle environments.

Vehicle compatibility and fitment

Designed for high-performance durability, this component is compatible with DAF, Mercedes-Benz, and Scania trucks. It operates effectively within the brake system to maintain optimal pressure levels, specifically suited for applications requiring a 24 V heater to prevent freezing in cold climates.

Technical specifications and installation

The technical configuration includes M22x1,5 ports (Port 1 and Port 21) and M16x1,5 ports (Port 22 and Port 4/23), with a standard operating pressure of 8.5 BAR. Technicians should verify these port specifications and electrical connections during installation to ensure proper fitment and prevent leaks.

Maintenance and troubleshooting

Regular inspection of the valve helps avoid moisture buildup that can lead to brake system malfunctions. For optimal performance, check the valve during routine service intervals to ensure all ports are clear of debris and the heater function remains operational.
